I don't see where this bummer is coming from.

The task is

Import request from Flask. Then update the index view to return "Hello {name}", replacing {name} with a name argument in the query string.

The code below throws bummer '/' gave a non-200 response. Did you change the route?

So I sense that there's something wrong with default route set up but I'm not entirely sure why I'm getting it. (I didn't change route)

The question seems not to expect to have app.run() so I didn't put it.

flask_app.py 
from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/')
def index(name='foo'):
    name = request.args.get('name', name)
    return "Hello {name}".format(name)

You are very, Very close. When using named fields in a format statement, the argument list must include the named reference. Change your return statement to:

    return "Hello {name}".format(name=name) #<-- Added argument name
